LAMPLOUGH DEVICE FOR JOINING ARTICLES Filed Dec. 4.1928 Myenfor [657/6 {la/77p dry/7 5/ M Patented Aug. 11, 1931 UNITEDSTATES PATENT OFFICE LESLIE FAWCETT LAMI'LOUGH, OF CHICAGO, ILLINOIS,ASSIGNOR TO WESTERN ELEC- TRIO COMPANY, INCORPORATED, OF NEW YORK, N.Y., A CORPORATION OF NEW YORK DEVICE FOR JOINING ARTICLES Applicationfiled December 4, 1928; Serial No. 323,596.

This invention relates generally to devices for joining articles, andmore particularly to devices for splicing wires.

The objects of the invention are to provide simple and effective devicesfor oining articles by means of which articles may be rapidly, uniformlyand securely joined.

In accordance with the general features of the invention, as embodied inone specific device by means of which a method embodying the inventionmay be practiced, there is provided a stationary jaw having a toothedgripping surface thereon, the central tooth of which extends beyond theother teeth, and a support is provided adjacent the stationary jaw forholding a tubular splic ng sleeve. A movable jaw having an openingtherein is provided adjacent the stationary jaw and the support and acam having suitable operating means associated therewith extends intothe opening in the movable aw to effect movement thereof. The movablejaw is also provided with a toothed surface for gripping the splicingsleeve, and means are provided for yieldably retaining this jaw incontact with the sleeve to hold the latter in a desired position.

Other objects and features of the 1nvention will be evident from thefollowing detailed description of a specific embodiment thereof, takenin connection with the accompanying drawings, in which Fig. 1 is a planview of a spliclng device by means of which the method embodying theinvention may be practiced;

Fig. 2 is a side view thereof;

Fig. 3 is an enlarged view of a partially formed splice formed by meansof the splicing device, and

Fig. 4 is an enlarged view of a completely formed splice.

Referring now to the drawings, the numeral designates a-base upon whichan L-shaped block 11 having an upwardly extending jaw portion 13 ispositioned by means of bolts 12-12 and uprights 1414 having notches15-15 and funnel-shaped depressions 1616 intersecting the slots 15-15formed therein are secured upon opposite sides of the block 11 bymeans-of splicing -toothed inserts 37 and 38 has just been inbolts 1818.Positioned between the uprights 14-14 is a bifurcated member 20 which isprovided with a horizontally disposed jaw portion 23 having alignedcircular openings 2121 formed in the arm portions 2222 thereof, intowhich openings a central cylindrical portion 24 of a cam 25 extends. Thecam 25 has aligned cylindrical end portions 26-26 formed thereoneccentrically of the cylindrical central portion 24, which end portionsextend into openings 2727 formed in the uprights 14-14 which act asbearings for the cam. An operating handle 30 extends into an opening 31formed in the central cylindrical portion of the cam 25 and issecuredtherein by means of a set screw 32 so that when the handle 30 isactuated the cam 25 is rotated and motion is imparted to the member 20,pins 34 and 35 which extend between the uprights 1414 serving to limitthe motion of the members.

A toothed insert 37 ispositioned in the jaw portion 23 of the member 20adjacent the slots 15-15 in the uprights 141-4 and a companion toothedinsert 38 is positioned in the jaw portion 13 of the block 11 oppositethe insert in the member 20, the central tooth 39 of which protrudesbeyond the other teeth forming a part of the insert 38 so as toinitially contact with and initially deform a tubular splicing sleeve41, which may be positioned between the inserts 37 and 38 and supportedupon a shoulder 42 formed on the block 11. Each of the arms 22-22 of thebifurcated member 20 is provided with an indentation 44 into whichspring pressed plungers 4545 mounted in the uprights 14-14 may extend toyieldably retain the member 20 in the position assumed by this memberwhen the tubular sleeve positioned between the itially deformed by theprotruding tooth 39 of the insert 38.

The operation of the device is as follows: The handle 30. is moved intothe position shown in Fig. 2, a splicing sleeve such as that indicatedby the numeral 41 is placed between the inserts 37 and 38 so as to restupon the shoulder 42, and the handle 30 44-44 in the arms 22-22 of themember-20,

at which time the central portion of the splicin sleeve 41 has just beeninitially deforme by the protrudin tooth 39 of the insert 38 in themanner s own in detail in Fig. 3. In this operation the sleeve 41 is griped by the inserts 37 and 38 and thereby lield against displacement, anda dent is formed substantially in the center of the splicing sleeve 41which acts as a stop against which'the ends of wires 47 and 48 to bespliced may be brought to position the ends equally within the splicingsleeve 41. After the ends of the wires to be sphced have been insertedwithin the initially formed splicing sleeve, the handle is advanoedstill further in a clockwise direction, as seen in Fig. 2, until themember 20 abuts the pin during which motion the splicing sleeve and theportions of the wires 47 and 48 positioned therein are deformed orcrimped in the manner showndn detail in Fig. 4, so that the wires areoined by means of the splicing sleeve 41.

It will be readily apparent that s1nce the cylindrical end portions26-26 of the cam 25 are rotatably mounted in the uprights 1414 and areformed eccentrically of the central cylindrical portion 24 of the cam,

the cam will exert force upon the member 1 20 when the cam is actuatedby means of the handle 30 andwill. cause the member 20 to reci rocate ina horizontal direction, and there y efi'ect relative movement betweenthe inserts 37 and 38. To assist in the insertion of wires within thesplicing sleeve positioned upon the shoulder 42 and in the withdrawal ofspliced wires from the device, the uprights 1414 are provided with slots15-15 and funnel-shaped depressions 16-16, through which the wires 1 maybe readily advanced.

Although a specific embodiment of the invention, by means of which wiresof circular cross-section may be spliced, has been described, it is ofcourse to be understood that the invention is not limited to thisspecific structure, but that wires and various other articles ofdifferent cross-sections may be joined by utilizing a device embodyingthe invention.
